It is not fixed for me: T500, 12.04.1 _LTS _. It causes severe
overheating and crashes on a regular basis. I even had problems
installing 12.04 due to crashes during the installation. Some things I
observed on my laptop:

- it is an OS specific bug: Windows works fine on my laptop
- the problem got worse from 10.04 to 12.04: I see approx. 10 degrees higher 
idle temperatures
- with Windows, higher fan RPMs seem to be available (below the very noisy 
full-speed) from what I can hear
- for me, the overheating problem seems to be severe only with discrete 
graphics (ATI) enabled
- I have thinkfan configured and running, but still have crashes (considerably 
less than without though)

It seems the debian bugfix fixes only a workaround (full-speed mode for
thinkfan).
